In humans, detached earlobes are dominant over attached earlobes. Do a
Punnett Square between 2 heterozygous people with detached earlobes. Give
the genotypic and phenotypic percentages of the offspring.
Please Help

The Punnet Square would be:

With E being detached earlobes and e being attached earlobes

EE, Ee, Ee, ee

So they would have a 75% chance of a child with detached earlobes and a 25% chance of a child with attached earlobes— If both parents are heterozygous.

name and explain one of the event that occurs during meiosis that increases the variation in offspring even more than simple reproduction?

some scientists like gregory adcock agree with thorne's theory of regional continuity.

others, like chris stringer and ian tattersall, believe thorne's results may be contaminated or misinterpreted.
